GM AD244 Style High Output 220 Amp Alternator - Black

Upgrade your LS truck charging system with this GM AD244 Style High Output 220 Amp Alternator engineered to deliver exceptional charging performance for vehicles with increased electrical demands. Designed for compatible GM LS truck accessory drive systems, this alternator provides the charging capacity needed to support modern performance upgrades, electrical accessories, and high-demand vehicle systems.

The 220 amp output provides a substantial increase over many factory charging systems and helps support electric cooling fans, electronic fuel injection systems, electric fuel pumps, aftermarket ignition systems, high-output lighting, air conditioning systems, audio equipment, winches, off-road accessories, and other power-hungry electrical components. Increased charging capacity helps maintain stable system voltage during idle, cruising, towing, and demanding operating conditions.

Built using the GM AD244 case design commonly found on many 1999-2006 GM truck applications, this alternator is designed for use with compatible LS truck accessory drive systems and factory-style AD244 mounting brackets. It is commonly used on 4.8L, 5.3L, 5.7L, 6.0L, 6.5L Diesel, 6.6L Duramax, and 8.1L applications where increased charging capacity is required.

The internally regulated design helps maintain consistent charging system performance while utilizing the factory-style 4-pin electrical connection commonly found on AD244-equipped applications. Unlike one-wire alternators, this design is intended to integrate with compatible factory-style charging system controls and wiring configurations.

Equipped with a 6-groove serpentine pulley and finished in bright chrome, this alternator combines show-quality appearance with dependable charging capability. Whether you're upgrading an LS-powered truck, supporting additional electrical accessories, building a tow vehicle, completing an LS swap with truck accessories, or replacing a factory AD244 alternator, this high-output alternator delivers the charging performance and reliability needed for demanding applications.
